Pee Gee Hydrangea - Knowledgebase Question

Pee Gee Hydrangeas produce flowers on new shoots which develop on old wood. You can prune in winter when the plant is dormant, or in very early spring, just as the leaf buds begin to swell. Cut the old canes down to about knee-high. New shoots will develop from these old canes and each shoot should produce at least one flower. Enjoy!
